The sensitivity parameter which is defined as a sum of partial derivatives is calculated with an accurate radiation code applying the 4-stream discrete-ordinates method and the method of exponential-sum fitting for gaseous transmission (ESFT). Microphysical properties of cirrus clouds are parameterized in terms of the cloud temperature from the data of aircraft observations. The value of ∂H/∂[IWC] x ∂[IWC]/∂T, i.e., a product of partial derivatives associated with ice water content feedback, is estimated to be 1.3-2.3 Wm-2°C-1, meaning a positive feedback effect, and the value of ∂H/∂[SD] x ∂[SD]/∂T which is associated with size distribution feedback is estimated to be -0.1--1.8 Wm-2°C-1, meaning a negative feedback effect. The positive ice water content feedback is significantly cancelled by the negative size distribution feedback especially at cloud temperature in the vicinity of -45°C. It is thus shown that the temperature dependence not only of ice water content but also of size distribution is important to estimate the microphysical feedback of cirrus cloud","subitem_description_type":"Abstract"},{"subitem_description":"巻雲の雲氷量と粒径分布の温度依存性を考慮して、気候変動における巻雲のフィードバック効果を調べた。偏微分の和として定義される敏感度パラメーターを、4ストリームのディスクリートーオーディネイト法とESFT法を用いて作成した高精度の放射コードで計算した。その際、飛行機観測データに基づいて雲氷量のフィードバックに関係した偏微分∂H/∂[IWC]×∂[IWC]/∂Tの値は 1.3-2.3Wm-2℃-1であり、雲氷量の温度依存性は正のフィードバックを引き起こす。一方、粒径分布に関係した偏微分 ∂H/∂[SD]×∂[SD]/∂Tの値は -0.1--1.8Wm-2℃-1であり、これは粒径分布の温度依存性によるフィードバックが負であることを意味する。特に巻雲が -45℃付近に存在する場合、雲氷量の正のフィードバックは粒径分布の負のフードバックによって相殺される。雲氷量のみならず粒径分布の温度依存性が巻雲の微物理課程のフィードバックの評価において重要であることを示した。","subitem_description_type":"Abstract"}]},"item_2_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"3895","nameIdentifierScheme":"WEKO"}],"names":[{"name":"鈴木, 恒明"}]},{"nameIdentifiers":[{"nameIdentifier":"3896","nameIdentifierScheme":"WEKO"}],"names":[{"name":"田中, 正之"}]},{"nameIdentifiers":[{"nameIdentifier":"3897","nameIdentifierScheme":"WEKO"}],"names":[{"name":"中島, 映至"}]}]},"item_2_publisher_20":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Meteorological Society of Japan"}]},"item_2_relation_25":{"attribute_name":"関係URI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"http://www.jstage.jst.go.jp/browse/jmsj/-char/en","subitem_relation_type_select":"URI"}}]},"item_2_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA00702524","subitem_source_identifier_type":"NCID"}]},"item_2_source_id_8":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"00261165","subitem_source_identifier_type":"ISSN"}]},"item_2_subject_15":{"attribute_name":"日本十進分類法","attribute_value_mlt":[{"subitem_subject":"451","subitem_subject_scheme":"NDC"}]},"item_2_text_21":{"attribute_name":"出版者別名","attribute_value_mlt":[{"subitem_text_value":"社団法人 日本気象学会"}]},"item_2_text_4":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"Center for Atmospheric and Oceanic Studies, Faculty of Science, Tohoku University"},{"subitem_text_value":"Center for Atmospheric and Oceanic Studies, Faculty of Science, Tohoku University"},{"subitem_text_value":"Center for Climate System Research, University of Tokyo"},{"subitem_text_value":"東北大学理学部大気海洋変動観測研究センター"},{"subitem_text_value":"東京大学気候システム研究センター"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Suzuki, Tsuneaki"}],"nameIdentifiers":[{"nameIdentifier":"3892","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Tanaka, Masayuki"}],"nameIdentifiers":[{"nameIdentifier":"3893","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Nakajima, Teruyuki"}],"nameIdentifiers":[{"nameIdentifier":"3894","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-05-30"}],"displaytype":"detail","filename":"1993_microphysical.pdf","filesize":[{"value":"5.0 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"1993_microphysical.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/954/files/1993_microphysical.pdf"},"version_id":"e8748f71-6bb2-4a1b-87d3-348b64e8a231"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"The microphysical feedback of cirrus cluod in climate change","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"The microphysical feedback of cirrus cluod in climate change"}]},"item_type_id":"2","owner":"1","path":["11","118"],"pubdate":{"attribute_name":"公開日","attribute_value":"2017-02-22"},"publish_date":"2017-02-22","publish_status":"0","recid":"954","relation_version_is_last":true,"title":["The microphysical feedback of cirrus cluod in climate change"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-19T03:42:13.402058+00:00"}
